The Neponset River Watershed is a resilient natural treasure.
Diverse landscapes, habitats, and species continue to flourish alongside 10,000 years of human impact and centuries of industrialization.
The Watershed includes parts of 14 cities and towns: Boston (Hyde Park, Mattapan, and Dorchester), Canton, Dedham, Dover, Foxborough, Medfield, Milton, Norwood, Quincy, Randolph, Sharon, Stoughton, Walpole, and Westwood.
The Watershed, by the numbers:
- A 29-mile-long Neponset River that starts in Foxborough, near Gillette Stadium, and ends in Dorchester/Quincy, near the “Rainbow Swash” gas tank by Route 93.
- A 120-square-mile area of land southwest of Boston that drains into the Neponset River, and ultimately into Boston Harbor.
- A home to 330,000+ people.
- A drinking water source to 120,000 people.
- A history that includes 10,000 years of human habitation and almost 400 years of industrialization.
Notable features include:
- the 29-mile-long Neponset River
- Neponset Reservoir
- Fowl Meadow
- Blue Hills
- Baker Dam
- Tileston and Hollingsworth Dam

We Thank Those Who Came Before Us
We acknowledge and honor the Indigenous communities who have nurtured the land and waters of the Neponset River Watershed for at least 10,000 years.
To our knowledge, the Neponset Watershed includes portions of the traditional lands of the Massachusett, Nipmuc, Pokanoket, and Wampanoag.
Our use and enjoyment of this area today are connected with their stewardship of it for many centuries and the history of their forced separation from their traditional homeland through colonization.
As you explore the Watershed, we encourage you to join us in actively learning about its past and current Indigenous heritage.
